There are a lot of sectors/frequencies missing from the high altitude chart, it looks like it only has the ultra high sectors on it. Is there another high sector chart that includes the rest of the high sectors ? DJ

Sector 75 only covers the western part of the area under Sector 76. The eastern half of the area under Sector 76 is covered by Low/High Sector 58, 126.350, which extends from the Surface/FL240/FL270 up to FL349. (note: the SOP lists the ceiling of Sector 58 as FL329, but from monitoring this frequency, the actual ceiling they are using is FL349, you show this as a low sector on your original map).

Missing Sector 66 (under Sector 65) FL240 to FL340 = 127.875

Sector 51 is an Ultra High Sector from FL380 and above. Sector 52, 135.050, is a Low/High sector from the surface to FL379, it covers the northern half of the area under Sector 51. Sector 35, 134.850, is a Low/High sector from the surface to FL379 that covers the southern half of the area under Sector 51.

That's what the SOP's show, but from monitoring both of those frequencies over the last few weeks they have been using them reversed, 132.825 in Sector 87 and 133.875 in Sector 78, that's current as of this morning. Maybe a temporary change ? Or maybe they keep switching them around like New York does in some of their sectors ? When it's slow they combine these sectors and use 133.875 as the primary for both.

ROFL, Im away from home for close to 90 hours a week. Pretty soon that will be close to 120 so it's not gonna give me more time to finish them up. I guess that Sunday: I must have been tired and slept real late...

From listening to JAX sector 34 there is an Ultra High Sector over that. From listening it is covering also sector 33. The freq is 128.625 and aircraft call it JAX Center. It would make sense because those two sectors does not have an Ultra High Sector like the other surronding sectors. From using Fight Aware I can confirm definetly that it is over sector 34 and somewhat sure over sector 33 as Flightaware shows delayed info.I am trying gather info for Miami Center as there is little info. It would be nice to have a map of Miami sectors. I looked at the sectors using Flight Explorer (demo free version) but it is not at all accurate. It is missing all Ultra High sectors. I can help monitor freqs for Miami center as I live in Tampa, FL

Miami has Ultra High sectors I was thinking that they didn't because there doesn't seem to be a heavy traffic presence transiting the Center. Since MCO and TPA would be at least a great part under 340 arrival wise as well as going into JAX center northbound there would not be much of a overly saturated traffic pattern. Well in any case I can let people know of my findings when I get to FLL next Sunday for 2 weeks. Scanner is coming with me this summer.

I can say this however from listening to PBI that the high frequencies from west to east would be 133.9-Gulf Oceanic,128.225-TPA TO RSW corridor,126.525-Central Fl,125.075-FLL TO MLB corridor,Oceanic south of the keys would be 132.2,126.325, and 135.225. Low wise I would say is 132.35(North)132.4(South) part of the TPA-RSW CORRIDOR,127.2(North)132.45(South) part of Central FL,126.95(North)135.175(South) part of the MLB-FLL corridor,Atlantic Oceanic would be 132.15,133.4,135.6,134.2 (Low Altitude) and 119.825,135.075,125.325,134.8(High Altitude)

"there doesn't seem to be a heavy traffic presence transiting the Center."

It is quite the opposite. I can monitor most of air traffic over Florida above FL160. Coming from the East coast is a lot of European traffic going across into Mexico and Central America. Going south is a lot of traffic going to Cuba, Jamaica, and the rest of the Caribbean. Heading north is traffic from the Caribbean.Going west to east across Florida is traffic from Mexico and Central America.The Ultra High Sectors in the Gulf of Mexico ZMA08 (CIGAR) 133.9, ZMA06 southof Gulf 132.2, north of Gulf of Mexico ZMA30 124.775. Going overland ZMA25 covers western coast 128.225. Eastern coast is ZMA02(Apollo) 125.325

I think we are changing the topic of the original thread from Jaxsonville to a Miami ATC subject, so I will respond back starting a new thread on Miami ATC, or the one you listed about Miami(previous thread) and gave reference to Radioreference ( which was a topic that I started on that website).Those freqs for Miami listed above are all Ultra High and I don't know as of yet anymore Ulta High for Miami. Due to the bad weather every day/afternoon sectors are not really working correctly/gets shut down/merge sectors so it it hard to figure out exact coverage area.
